FIELD OF THE INVENTION

This invention relates to gel products that are useful to reduceunderarm wetness. Optionally they can include antiperspirant and/ordeodorant agents, but are particularly advantageous in providingdeodorants that have reduced wetness without the use of anantiperspirant active. Reference is made to a case filed on the same dayas this case and referenced as Attorney Docket Number IR 6754-00.

BACKGROUND OF THE INVENTION

A variety of technologies have attempted to use superabsorbent polymersof various types in a wide variety of applications. These technologiesinclude the construction of diaper products for children and adults, andthe use of superabsorbent polymers to clean up liquid spills. Theproblems associated with the use of such polymers in personal careapplications include a wet and sticky feel and skin irritation.Additionally, it has been difficult to find a way of applying suchproducts in the underarm area in a way that results in an aestheticallyacceptable product form. It has now been found that selected water locksuperabsorbent polymers in certain formulations both with and withoutantiperspirant or deodorant agents may be used to create superioranti-wetness products.

It is also desirable to have the ability to reduce wetness using adeodorant product. While some deodorants contain lesser amounts ofantiperspirant actives, there is a segment of the population thatprefers to use deodorants that do not contain antiperspirant actives. Itwould be advantageous to provide a product that reduces wetness withoutthe use of antiperspirant actives.

BRIEF SUMMARY OF THE INVENTION

The invention comprises an underarm product suitable for use to reducewetness under the arm. It may be viewed as providing some deodorancyeffect. Optionally, a portion of an antiperspirant active may beincluded to provide an antiperspirant/deodorant. This underarm productmay be a gelled stick or a soft gel which comprises a water locksuperabsorbent polymer selected from the group consisting of starchgraft homopolymers and copolymers of poly(2-propenamide-co-2-propenioicacid) sodium salt. While these homopolymers and copolymers may be usedin a variety of particle sizes, it is generally believed that thesmaller sizes are preferred (for example, having 95% of the particlesable to go through a 60 mesh screen (comparable to a size of 250microns)). The formulations of the invention may be made asantiperspirants and/or deodorants. In the case of antiperspirants, theproducts give an extra measure of protection against wetness. In thecase of deodorants, the products may be made with low levels ofantiperspirant active or with other agents which provide a deodorizingeffect but which are not antiperspirant salts.

For the antiperspirant active used in the active phase variousantiperspirant active materials that can be utilized according to thepresent invention provided that they are soluble at a suitableconcentration in the water and/or glycol component (also called theactive phase). These include conventional aluminum andaluminum/zirconium salts, as well as aluminum/zirconium salts complexedwith a neutral amino acid such as glycine (“gly”), as known in the art.See each of European Patent Application Number 512,770 A1 and PCT caseWO 92/19221, the contents of each of which are incorporated herein byreference in their entirety, for disclosure of antiperspirant activematerials. The antiperspirant active materials disclosed therein,including the acidic antiperspirant materials, can be incorporated inthe compositions of the present invention if they are soluble in theactive phase. Suitable materials include (but are not limited to)aluminum chlorohydroxide, aluminum chloride, aluminumsesquichlorohydroxide, zirconyl hydroxychloride, and aluminumchlorohydrol-propylene glycol complex. These include, by way of example(and not of a limiting nature), aluminum chlorohydrate, aluminumchloride, aluminum sesquichlorohydrate, zirconyl hydroxychloride,aluminum-zirconium glycine complex (for example, aluminum zirconiumtrichlorohydrex gly, aluminum zirconium pentachlorohydrex gly, aluminumzirconium tetrachlorohydrex gly and aluminum zirconium octochlorohydrexgly), aluminum chlorohydrex PG, aluminum chlorohydrex PEG, aluminumdichlorohydrex PG, aluminum dichlorohydrex PEG, aluminum zirconiumtrichlorohydrex gly propylene glycol complex, aluminum zirconiumtrichlorohydrex gly dipropylene glycol complex, aluminum zirconiumtetrachlorohydrex gly propylene glycol complex, aluminum zirconiumtetrachlorohydrex gly dipropylene glycol complex, and mixtures of any ofthe foregoing. The aluminum-containing materials can be commonlyreferred to as antiperspirant active aluminum salts. Generally, theforegoing metal antiperspirant active materials are antiperspirantactive metal salts. In the embodiments which are antiperspirantcompositions according to the present invention, such compositions neednot include aluminum-containing metal salts, and can include otherantiperspirant active materials, including other antiperspirant activemetal salts. Generally, Category I active antiperspirant ingredientslisted in the Food and Drug Administration's Monograph on antiperspirantdrugs for over-the-counter human use can be used. In addition, any newdrug, not listed in the Monograph, such as tin or titanium analogues ofthe aluminum slats listed above, aluminum nitratohydrate and itscombination with zirconyl hydroxychlorides and nitrates, oraluminum-stannous chlorohydrates, can be incorporated as anantiperspirant active ingredient in antiperspirant compositionsaccording to the present invention. Preferred antiperspirant activesthat can be incorporated in the compositions of the present inventioninclude the enhanced efficacy aluminum salts and the enhanced efficacyzirconium/aluminum salt-glycine materials, having enhanced efficacy dueto improved molecular distribution, known in the art and discussed, forexample, in PCT No. WO92/19221, the contents of which are incorporatedby reference in their entirety herein.

Antiperspirant actives can be incorporated into compositions accordingto the present invention in amounts in the range of 0-10% (on ananhydrous solids basis), preferably 5-10%, by weight, of the totalweight of the composition. The amount used will depend on theformulation of the composition. For example, at amounts in the lower endof the broader range (for example, 0.1-5%), the antiperspirant activematerial will not substantially reduce the flow of perspiration, butwill reduce malodor, for example, by acting as a deodorant material, forexample, by acting as an antimicrobial or complexing with the malodorouscomponents of human perspiration. Deodorant active materials can includelesser amounts of antiperspirant actives, such as in the range of0.1-5%, as well as fragrances, and effective amounts of antimicrobialagents, for example, bacteriostatic quaternary ammonium compounds (suchas cetyl trimethyl-ammonium bromide, and cetyl pyridinium chloride),2,4,4′-trichloro-2′-hydroxydiphenylether (Triclosan),N-(4-chlorophenyl)-N′-(3,4-dichlorophenyl)urea (Triclocarban), silverhalides, octoxyglycerin (SENSIVA™ SC 50) and various zinc salts (forexample, zinc ricinoleate) may also be included in formulations of thepresent invention. The bacteriostat can, illustratively, be included inthe composition in an amount of 0.01-5.0% by weight, of the total weightof the composition. Triclosan or Triclocarban can, illustratively, beincluded in an amount of from 0.05% to about 5.0% by weight, of thetotal weight of the composition.

Volatile silicones and silicone surfactants are also used in theinvention.

By volatile silicone material is meant a material that has a flash pointof 100 degrees C. or less at atmospheric pressure. Such volatilesilicones include conventional cyclic and linear volatile silicones suchas cyclomethicone (especially cyclopentasiloxane, also called “D5”),“hexamethyldisiloxane”, and low viscosity dimethicone (for example, DowCorning® 200 fluid having a viscosity of 0.5-5 centistokes).Illustratively, and not by way of limitation, the volatile silicones areone or more members selected from the group consisting of cyclicpolydimethylsiloxanes such as those represented by Formula III-S:

where n is an integer with a value of 3-7, particularly 5-6. Forexample, DC-245 fluid (or the DC-345 version) from Dow CorningCorporation (Midland, Mich.) is a type of cyclomethicone which can beused. These include a tetramer (or octylmethylcyclotetrasiloxane) and apentamer (or decamethylcyclopentasiloxane). The volatile linearsilicones can also be included in this group of volatile silicones andare one or more members selected from the group consisting of linearpolydimethylsiloxanes such as those represented by Formula IV-S:

and t is selected to obtain a viscosity of 0.5-5 centistokes.

Examples of such volatile silicones include one or more members selectedfrom the group consisting of D4, D5, and D6 cyclomethicones; and lineardimethicones having a viscosity in the range of 0.5-5 centistokes.Preferably the oil phase is a mixture of one or more of D4, D5 and D6cyclomethicones.

Suitable silicone surfactants include silicone polyglucosides (forexample, octyl dimethicone ethoxy glucoside) and silicone copolyolshaving an BLB value (hydrophilic lipophilic balance) in the range of3-13. A silicone copolyol (especially dimethicone copolyol) may be usedin an amount of 0.05-5.0 weight % (actives basis), particularly 0.5-5.0%and, more particularly, 0.5-3.0%.

In general, silicone copolyols useful in the present invention includecopolyols of the following Formulae I-S and II-S. Formula I materialsmay be represented by:

(R¹⁰)₃—SiO—[(R¹¹)₂—SiO]_(x)—[Si(R¹²)(R^(b)—O—(C₂H₄O)_(p)—(C₃H₆O)_(s)—R^(c))O]_(y)—Si—(R¹³)₃  FormulaI-S

wherein each of R¹⁰, R¹¹, R¹² and R¹³ may be the same or different andeach is selected from the group consisting of C1-C6 alkyl; R^(b) is theradical —C_(m)H_(2m)—; R_(c) is a terminating radical which can behydrogen, an alkyl group of one to six carbon atoms, an ester group suchas acyl, or an aryl group such as phenyl; m has a value of two to eight;p and s have values such that the oxyalkylene segment—(C₂H₄O)_(p)—(C₃H₆O)_(s)— has a molecular weight in the range of 200 to5,000; the segment preferably having fifty to one hundred mole percentof oxyethylene units —(C₂H₄O)_(p)— and one to fifty mole percent ofoxypropylene units —(C₃H₆O)_(s)—; x has a value of 8 to 400; and y has avalue of 2 to 40. Preferably each of R¹⁰, R¹¹, R¹² and R¹³ is a methylgroup; R^(c) is H; m is preferably three or four whereby the group R^(b)is most preferably the radical —(CH₂)₃—; and the values of p and s aresuch as to provide a molecular weight of the oxyalkylene segment—(C₂H₄O)_(p)—(C₃H₆O)_(s)— of between about 1,000 to 3,000. Mostpreferably p and s should each have a value of about 18 to 28.

A second siloxane polyether (copolyol) has the Formula II-S:

(R¹⁰)₃—SiO—[(R¹¹)₂—SiO]_(x)—[Si(R¹²)(R^(b)—O—(C₂H₄O)_(p)—R^(c))O]_(y)—Si—(R¹³)₃  FormulaI-S

wherein p has a value of 6 to 16; x has a value of 6 to 100; and y has avalue of 1 to 20 and the other moieties have the same definition asdefined in Formula I-S.

It should be understood that in both Formulas I and II shown above, thatthe siloxane-oxyalkylene copolymers of the present invention may, inalternate embodiments, take the form of endblocked polyethers in whichthe linking group R_(b), the oxyalkylene segments, and the terminatingradical R^(c) occupy positions bonded to the ends of the siloxane chain,rather than being bonded to a silicon atom in the siloxane chain. Thus,one or more of the R¹⁰, R¹¹, R¹² and R¹³ substituents which are attachedto the two terminal silicon atoms at the end of the siloxane chain canbe substituted with the segment —R^(b)—O—(C₂H₄O)_(p)—(C₃H₆O)_(s)—R^(c)or with the segment —R^(b)—O—(C₂H₄O)_(p)—R^(c). In some instances, itmay be desirable to provide the segment—R^(b)—O—(C₂H₄O)_(p)—(C₃H₆O)_(s)—R^(c) or the segment—R^(b)—O—(C₂H₄O)_(p)—R^(c) at locations which are in the siloxane chainas well as at locations at one or both of the siloxane chain ends.

While aconcentration of 10% in cyclomethicone is frequently seen commercially,other concentrations can be made by stripping off the cyclomethicone oradding additional cyclomethicone. The higher concentration materialssuch as DOW CORNING® 2-5185 material is of particular interest.

In one particular embodiment 0.5-50 weight % (particularly 10-30%) of a10% silicone copolyol such as dimethicone copolyol in cyclomethiconemixture may be used, wherein the amount of mixture added is selected sothat the level of silicone copolyol in the cosmetic composition is inthe range of 0.05-5.0% (particularly 0.1-3.0%).

Non-volatile silicones having a flash point greater than 100 degrees C.may also be used in the formulations of this invention. Such nonvolatilesilicones are those which are not under the definition of volatilesilicones and include linear organo-substituted polysiloxanes which arepolymers of silicon/oxygen with a general structure:
